<pre>Please attach your xorg log and dmesg output. Note that using the dGPU
involves extra copies to copy the rendered frame to the integrated GPU for
display so there is additional overhead. You need a relatively advanced 3D
game to see an advantage on the dGPU as you have to overcome the overhead of
the additional copies.</pre>
